Blue Lock Chapter 308 spoilers recap
Titled “Cocky/Arrogant Chicken,” Chapter 308 begins with Hirotoshi Buratsuta confronting Seishiro Nagi in the rain. Buratsuta offers Nagi a backdoor route into the Blue Lock Japan team by becoming part of the “Buratsuta 3,” a trio selected outside Ego Jinpachi’s picks. He explains the roster limit for the U-20 World Cup is 26, and he holds authority over three additional slots.
Buratsuta outlines conditions for selection: passing a private test, surrendering all management decisions to him, and proving Ego’s methods wrong. Nagi declines, stating he cannot betray Blue Lock, and credits Ego for igniting his passion with Reo. Buratsuta calls him a “pride-bloated fool” as Nagi walks away.
Soon after, Buratsuta receives a call from Sae Itoshi, who confirms Japan’s group stage opponents: Nigeria, England, and France. Sae accepts one of Buratsuta’s three spots but states he will only join to face Spain. He agrees to join Team Japan after finishing his finals. He then declares his intention to use Blue Lock to achieve his personal goals.
